without the word exactly included, if a statement is true, then so are all preceeding statements (if 3 are false, then AT LEAST 2 are false etc.), so this boils down to only 10 situations - which is the highest numbered true statement? Using my favorite analytical method (brute force), the first five statements are true, and 6 through ten are false.
btw, if not obvious, when the "exactly" is included, there is only one true statement, and it's #9.
